RAI LWAY-GATE.

SPECIFICATION forming' part of Letters Patent No. 295,358, dated March18, 1884.

Application filed October 30, 1853. (No model.)

To all? whom t may concern,.-

Beit known that I, Dxvrn W. CorELAND, of Lowville, in the county ofLewis and State of New York, have invented a new and usefulImprovementinRailWay-Gates; and I do hereby declare that the followingis a full, clear,

oted a bell-crank lever, D, which, by means of and exact description ofthe same.

My invention relates to gates of that class in which the gate isautomatically moved or slides by gravity on a Way which is tilted by thepassing vehicle, either to open or close. Its object is to simplify thedetails and to render the gate, under all circumstances, certain in itsoperation.V

The invention consists in details of construction, all as hereinafterfully set forth, and shown -in the accompanying drawings, in whichFigure l represents the gate in side elevation. Fig. 2 shows across-section of the shifting track, with an end view of the carriagethat supports the gate. Fig. 3 represents a cross-section of the track,with an end view of the gatefframes. Fig. 4 is a plan view ofthe trackwith connecting mechanism for the gate and moving parts exposed. Fig. 5represents the movable tread and its connection with the Working-leversof the mechanism which moves the gates. Fig. 6 is a plan of thelever-connections, with the top ofthe box removed.

In Fig. 1,Arepresents the posts of the gateframe, which posts areconnect-ed by a crossbar, c.. On the central post is pivoted a tiltingbar, B,whic`h is the gate-track. It tipsin vertical plane, and on it runWheels b b, from which are hung the gate by means of ha-ngers c c. Thehangers are connected by a rigid bar, C, and have a series of holes foradjusting the gate vertically. This practically constitutes a truck,upon Whichthe gate hangs. The gate consists ot' vertical slats d d,connected to the hangers by hooks c e and to each other byrpivotedcrossbars f f. The gate has some ilexibility, and .always hangsvertical. It may run from one end of the track to the other, and theends of the track are inclined upon the track: v surface, as shown at gg. This gives a horizentral surface for one roller to rest upon, asshown on the left of Fig. l, and a greater inoline when the end israised, as shown in Fig. l on the right hand. The gate is moved by thetipping of its track. This is accomplished by connection with the motiveparts at one end of the bar. These connections are shown in Figs. l and2 as far as the transverse connect-ions extend.

In a box at one end ofthe gate-frameis pivrod h, is connected tobell-crank lever E near the track, and in a chamber, k, beneath thesurface. From this latter bell-crank lever rods extend to a box, H,hereinafter explained. The bellcrank lever D is connected to thegate-track through an intermediate lever, Z, by means of rods m m. Thisis for the purpose of compensating for the contraction and expansion ofthe rods, due to atmospheric changes in temperature. The lever Z ispivoted upon the post, and the track-bar is pushed up to throw the gatein one direction, and drawn down to throw it in the opposite direction.For doubletrack roads-such as .that shown in Figs. 3 and Lithe gates anddescribed connections are duplicated, as represented.

On a vertical shaft in the trunk or chamber is pivoted the bell-cranklever E, and to that arm ot' said lever which extends at right angles tothe track is attached the longitudinal rod, chain, or rope o, whichpulls the lever when the train passes over the inclined treadle.` One ofthese ropes or rods runs in each direction. Each is connected to abell-crank lever, G, at a distance from the gate of onefourth of a mile,more or less. This bellcrank lever is pivoted in a box, H, to Swinginvertical plane. The horizontal arm is connected, as shown in Fig. 5, toa lever, p, pivoted on a shaft, t. The spring-tread M is connected tothis lever p, between its pivot and the bearing upon the bell-crank, bymeans ot a post, r. Thus when the tread is depressed by the tread of theWheel, the lever p is caused to operate in the train of levers and rods,and forces the gate to open or close, as the case maybe. One tread inthe example shown closes the gates as the train approaches the crossing,and, after the train has passed,anothcr, located on the same track anequal distance from the crossing, opens the gates.

It will be understood that there is a gate on IOC each side for avsingle track; or one alone may be used, if desired; and, as shown in theiigures, two gates are provided for double tracks. The gates and theirconnections are duplicates. This prevents any liability of clashing bytrains passing in opposite directions.

The rods or ropes may be laid in any suitable pipes. track I use stiffrods, so that the bell-crank E, when it is drawn in one direction, maypull, and in the other may push upon the track-bar.

The post r, being between the fulcrum and weight, is adapted to multiplythe motion of the spring-track.

The gate, moved in the manner described upon a track, runs gently, andthere is no danger of collision with carriages which may happen to beinthe way of the gate. 'Ihe gate may be arrested by hand at any point, ormay be opened and closed' freely by hand.

In Fig. 3 two levers, E, are shown. To the upper of these the rods 1L 7ifrom one setl of gates are attached, and to the lower the rods ofanother set of gates, as shown in this ligure and in Fig. 4, these rodsleading to one set of gates.4 From the transverse end of this lever rodsor ropes run in two directions to the opening and closing mechanisms ofone track.

The apparatus hasbeen described as applied to a railway. The gate andits moving apparatus, with very little and obvious modification, is alsoapplicable to vordinary wagonroads.

I claiml. A gate suspended from wheels, in combination with a track-barfor the wheels, piv- Between the lever E and the gate- -sideof atrack-adapted to slide on a pivoted track-bar, bell-crank levers D, andconnections therefrom to the ends of the bars, rods h 5o l1., andbell-crank levers E,with rods or ropes, and means wherebythe wheels ofthe car operate the mechanism, all substantially as described.

4. In the described relation to the gates and their connecting-rods andlevers, and in combination, the bell-crank lever G, connected lever p,pivoted to q, post r, and spring-treadle, all substantially asdescribed.

5. In the described gate, the combination of 6o the wheels b b, hangersc c. perforated, as described, bar C, and the gate-frame propersuspended from hangers c c, and adapted to be adjusted verticallythereon, substantially as described.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
